When the cradle 1-3 is in operation, the cradle 1-3 carries the strands in a rotational movement around the thigh pan 3-14 and winds the strands around the thigh pan 3-14. If the lay length of the strand is too great, the core diameter of the strand disc is too small, the strand will not have winding tension when wound around the strand disc, and the strand length of the lay length is greater than the circumference of the core of the strand disc. The strand disc power shaft 3-3, the tension transmission gear 3-4, the strand disc poking gear 3-5 and the tension control duplex gear 3-6 form a differential gear set, when the twisting distance of the strand is too large and the diameter of the inner core of the strand disc is too small, the strand disc 3-14 will give power to the tension control duplex gear 3-6, and the tension control duplex gear 3-6 will transmit power to the tension transmission gear 3-4. The tension transmission gear 3-4 is connected with the strand disc power shaft 3-3 in a key way, and the strand disc 3-14 feeds back power to the sprocket wheel 3-2 on the strand disc power shaft 3-3 and feeds back power to the magnetic powder clutch 3-1 to control tension.
